alright, i've finally got this thing lined up into components, split into very close approximations of snapshots in april, may, june and july of 2002 - as well as snapshots in 2007 and 2009. what that means is i can build up each snapshot mix by successively activating each folder.
now, i just need to mix the parts.
but i seem to have not slept well last night, so it'll be when i wake up. i think i'm only a few hours away from getting this, though.
it's probably because i spent four hours walking through london, and four hours on the bus. long day yesterday....
